IMPROVEMENT lN BREECH-LOADING FIRE-ARMS.

Specification forming part of Letters Patent N 0. 114,230, dated April25, 1871.

To all whom it may concern.-

CHARLES GERNER,

cut, have invented to the accompanying drawing.

Our invention relates to breech-loading guns; and 1t conslsts in a novelarrangement of devices for operating the extractor, whereby the same ismade to partially expel the cartridge-shells by tipping the barrel orbarrels, and then returning the extractor to its place again, all ashereinafter more fully explained.

It further consists in beveling the shoulders of the joint in the frame,so as not to pinch the hand in opening the breech.

Figure l is a longitudinal section, with the barrels in position forfiring. Fig. 2 is a similar view, showing the barrels tipped and theextractor shoved out. Fig.3 is a view of a portion shown more in detail.

The general construction of the gun is the same as that patented toWhitney, Gerner 8s Tiesing, in which the barrels B are secured to an armor frame, E, projecting from the front of the breech A at its lowerside, and in which arm there is a joint, to permit the barrels to tip upat the breech in a manner well known, and as represented in Fig. 2.

This stem 0 fits in a hole bored for it in a lug secured to the underside of the barrels, at the center, and it extends forward to the joint,as represented in Figs. 1 and 2, it having a recess or notch out in itsunder side, near its end, as shown in the drawing.

In the center of the frame E, at the joint, is located a plate, D, whichis mounted loosely on the joint-pin a, this plate having a projectron orarm, 2', on its upper edge, which fits into the notch in theextractor-stem C. It also has on its front edge another arm orprojectlon, e, upon which bears a spring, '12, secured to the front partof the frame E. On its rear face, at its lower edge, it also has a notchcut,

so as to form a shoulder, against which the end of a spring-pawl, It,bears, this pawl k being secured to the rear part of the frame E, asshown in Figs. 1 and 2.

The rear end of the front part of the frame E has its under side out onan incline or bevel, as represented at 0, Fig. 3, and by dotted lines inFigs. 1 and 2, this incline, at its lower or front end, coming out flushwith or a little beyond the extreme edge of the plate D, so

that as the barrels, with the front part of the frame E, are throwndown, this incline will bear upon the pawl h, and disengage it from theshoulder c of the plate D, as represented in Fig. 2, the pawl It beingwider than the plate D is thick, so as to protrude at each side, andpermit the inclines 0 to hit it as the barrels are tipped.

It will be observed that the shoulders r of the frame E, where the jointis made, are each beveled off, as shown in Figs. 1 and 2, so that whenthe breech is opened they will not catch and pinch a times done by gunsof this class.

It is obvious that these improvements may be applied to either single ordouble barreled guns.

With the ranged, the operation is as follows: The gun having been firedwith the barrels in the position represented in Fig. 1, the barrels arereleased or unlocked from the breech A, when they tip forward to theposition shown in Fig.

.7 2. The pawl h, being then in the notch 0,

holds the plate D, and prevents it from turning on the pin a, and as itis thus held, with its arm 2' in the notch of the stem 0, it forces theextractor out, as represented in Fig. 2, as the barrels tip forward.

As the barrels and front part of the frame move, the incline 0 forcesthe pawl h off from the shoulder c, which is thus released, when, atonce, the spring a, pressing on the arm 0, causes the plate D to rotateslightly on the pin a, and thereby draw the extractor back again to itsoriginal position.

As the barrels are again closed, the plate D is moved backward, and justbefore thebarrels are closed the pawl it again springs into portion ofthe hand, as is someparts thus constructed and arthe notch c, theinclines 0 having been moved forward out of its way by the closing ofthe barrels.

In this way we produce an automatic move- "ment of the extractor by theuse of devices that are simple, strong, and not liable to get out oforder, and which insure the return of the extractor to its seat afterhaving expelled the shells, ready for reloading the gun.

Having thus described our invention, what we claim is- 1. The plate D,connected to the extractorstem 0 by the arm 15, and having the arm 0,
